Where to position exterior fans for Dometic Fridge?

[SarahW]

I have read many posts on the benefit of adding small fans to help circulate air behind the Dometic refrigerator. Exactly where are these mounted? Thanks.

I don't have a Dometic but I do have a Norcold and I mounted mine pointing straight up in the back... I used 2 computer cooling fans, I have to turn them off and on manually but it seems to work OK.......

Thanks, Lee. Did you pull the fridge out or install the fan from the vent outside the RV? I'm having trouble picturing the installation. (duh)

Interested too. , as our fridge is in our galley slide so intake and exhaust are on the slides side.

Hmm, get a12 v fan or 110 ?
Mount it in the lower vent pointing up or one in the lower and one in the upper?

I installed computer fans on mine from the outside. Used nylon cable ties to secure them at the bottom blowing air up over the coils. You pretty much have to use whatever you can find to secure the fans to.

According to Norcold, Dometic and Fantastic Vent the fans should be mounted at the outlet and pull the air over the coils, not blow in from the bottom. It's more efficient that way.

The first post of this link shows where GaryKD installed his fan on his Dometic fridge.
He found no fans on his fridge as the Norcold has.
Its also advisable to check the rear vent area of fridge and see if you have a clear path up through vent area and out the roof vent sometimes a baffle or insulation will slip off top of fridge and block the upper vent area.
You may not have a baffle as required by fridge mfg installed per their insulation spec's.
There is 12v in rear area of fridge for fan and you can use thermal switch or just leave fan on all the time fridge is on.
Some people have installed fans on cooling fins inside box portin of fridge to cycle cool air around in box.
The more heated air to escape the vent area the colder the box will be, the freezer will get colder also.
